After helping Chen Xu buy suits, the three of them played in Sanlitun until eleven o'clock before returning to the Convention and Exhibition Center.

The next morning it rained heavily in Kyoto, and the sky, which had been looking gray until now, was as clean as a wash, with a smell of earth.

After breakfast, Chen Yiyi went to school one by one, and Shen Yiqiu went to find his high school classmates.

Chen Xu stood in front of the window of the smoking room on the second floor of the hotel, lit a cigarette, looked at the health and beauty salon opposite, and felt the smoke burn his lungs after passing through his nasal cavity, and then spewing out of his mouth.

There was a sound of footsteps behind him, an old man in a suit and leather shoes with half-white hair, with a national emblem pinned to his chest, walked to Chen Xu's side and lit a cigarette with a "click".

may have seen that Chen Xu was also in a suit and leather shoes, and the old man looked at the water droplets dripping from the eaves outside and said, "The air here in Kyoto is not good." ”

Chen Xu said: "Yes, it's not as refreshing as our hometown. ”

Old man: "Where is your home?"

Chen Xu: "Su Province." ”

Old man: "The economy of Suzhou Province is good, and the development of Hunan Province is much better than that of our Hunan Province." ”

Chen Xu: "Well, the heavy industry in Hunan Province is still okay, that is, the high-end industry, such as the emerging information industry, the electronics industry, and the automobile industry. ”

The old man shook his head, "The sales revenue of heavy industry has been declining year by year, from 2013 to the present.

In addition, the high-end industry is not very good, but something that can be done at all.

You like Jiangcheng, Luzhou, Chang'an, these are seizing the opportunity of the development of large semiconductors, BOE, Unisplendour in these places have a lot of investment. Like the wafer industry, the agglomeration effect is very strong. ”

Chen Xu said with a smile: "We must find ways to promote the development of high-quality industries. ”

The old man sighed and said: "It's difficult! These things are not achieved overnight, the key is to have technology, without technology, if you give you 100 million, 10 billion, you can't create the corresponding industrial value, it is also equal to 0." ”

Chen Xu nodded and extinguished the cigarette in his hand.

The old man took out a box of hard-shelled Hibiscus King from his pocket, took out one and handed it to him.

"Thank you~" Chen Xu took it, clicked it again, and then took out the soft middle and scattered it for the old man.

The old man was not polite to him, and asked, "What are you doing here?"

Chen Xu: "Participate in academic seminars. ”

Old man: "Oh, what kind of seminar?"

Chen Xu: "Artificial intelligence. ”

Old man: "Artificial intelligence is good, this is the general trend of future development. ”

Chen Xu: "Yes, you are right, artificial intelligence is like the nuclear power of a giant warship, which will drive the development of the whole industry......"

Two people, two cigarettes, and talked for ten minutes.

When they finished their cigarettes, they left.

……

Today's meeting is still boring for Chen Xu.

Still, he insisted on sitting down.

In the evening they went to Houhai.

During the day, it looks at Houhai like that, and at night it reveals its charming style, with tourists weaving, with the music from the bar, forming its unique style.

Play until eleven o'clock and return to the hotel.

The next morning, Chen Xu was still sleeping in a daze, when the door was smashed.

Chen Xu rubbed his head, looked at the time, it was only four o'clock in the morning, got up and walked to the door and shouted, "Who?"

Chen Yiyi's voice sounded outside, "Brother, didn't you say you were going to watch the flag-raising ceremony, get up quickly." ”

"Oh, yes~" Chen Xu opened the door, turned around and walked towards the bathroom, "Wait for me for three minutes." You go and call Shen Yiqiu. ”

Chen Yiyi said: "You big lazy pig, people have already gotten up and are waiting for us in the lobby downstairs." ”

"Oh oh oh~" Chen Xu quickly brushed his teeth and washed his face, put on a set of jackets, jeans and sneakers, took the computer and mobile phone room card and said, "Let's go." ”

Tomorrow is May Day, and there must be a lot of people watching the national flag raising, and they usually have to line up there all night.

Chen Xu wanted to go and see it in advance.

The time of the national flag-raising ceremony in Tiananmen Square in Kyoto is not fixed, and it varies from day to day.

From January 11 to June 6 every year, the flag-raising is gradually advanced from 7:36 a.m. to 4:36 a.m., with an average of about 1 minute earlier every day.

From June 22 to December 30, the flag-raising time was gradually postponed from 4:46 to 7:36, with an average of 52 seconds per day.

From December 31 to January 10 and from June 7 to June 21, the flag-raising time is constant at 7:36 and 4:46 respectively.

Tiananmen Square is closed at night, and it is generally opened about 40 minutes earlier than the flag-raising time in the morning, and it is generally queued up at the scene an hour in advance, because you need to swipe your ID card to enter the scene.

There are a total of 3 viewing points in the square. They are south of the cordon on the south side of the flagpole on the square, east of the cordon on the east side of the Jinshui Bridge, and west of the cordon on the west side of the Jinshui Bridge.

This morning's flag-raising ceremony is at 5:16 a.m.

Maybe because tomorrow is May Day, there are already a lot of foreign tourists who come in advance, and the scene is crowded, holding mobile phones and cameras to take pictures, and there are children waving small national flags in their hands.

Chen Xu and the others came to the west of the cordon on the west side of Jinshui Bridge at 4:40, and the location was not very good.

The waiting time was not long, at 5:16, on time and on time, not a second was bad, and the flag bearer came out of Tiananmen Square.

Adults and children at the scene were screaming excitedly, "Ah...... It's out, it's out......"

The flag bearers walked all the way to the bottom of the flag-raising stand and began to play the national anthem.

When the music sounded, the noisy scene suddenly fell silent, and everyone paid attention with the solemnity of pilgrimage.

Chen Xu didn't know what was going on, and suddenly his heart was full of blood, and he sang silently in his heart with the sound of music.

Rise up ~ people who do not want to be slaves

Build our flesh and blood into our new Great Wall

The Chinese nation has arrived, the most dangerous time

Everyone was forced to let out a final roar

Get up~Get up~Get up~

We marched as one, braving enemy fire

Brave enemy fire to advance, forward, forward, advance!

When the music ended, Chen Xu blinked his eyes twice.

Then he turned his head and saw that he was not alone, and several tourists who were obviously coming for the first time were inadvertently rubbing the corners of their eyes.

"Let's go......"

……

……

At 9 o'clock in the morning, in the multi-functional staircase conference hall of the Kyoto Science and Technology Exhibition Center, the academic seminar on natural language processing began as usual.

The first to give a presentation was an expert from the University of Toronto, Canada.

The half-hour speech report on "Language Cognitive Model" received warm applause from many experts and scholars at the scene.

The second is a scholar from the University of Tokyo.

The topic of his speech was "Language Representation and Deep Learning", and the wonderful speech was also full of applause.

There was a twenty-minute break in between, and at 10:20 the meeting resumed.

This time it was none other than Professor Liu Chenglin, vice president of the China Computer Association and the host of the meeting.

"Ahem~ Now I want to introduce a person to you, his name is Chen Xu, and he is also my student, this is a young man with extraordinary talent in the field of natural language processing!"

Saying that, Liu Chenglin looked in the direction of Chen Xu's doing, and said with a smile: "You can come over." ”

As Liu Chenglin's words fell, the audience looked at Chen Xu.

Chen Xu stood up with a shy smile, and then walked quickly towards the podium under the staircase conference room under Chen Yiqiu's gaze.

Along the way, there were doubts and curious eyes everywhere.

Chen Xu came to the podium and said, "Hello teacher!"

Liu Chenglin nodded with a smile, and then said: "Many people may be questioning, why I want to introduce him to everyone, let him explain this question himself." ”

Saying that, Liu Chenglin gave up the podium position.

"Thank you, teacher~"

After thanking Professor Liu Chenglin, Chen Xu watched Professor Liu Chenglin return to the audience, then took out a USB flash drive from his pocket and connected it to the LCD tablet on the podium, adjusted to today's copywriting outline, patted the microphone and said: "First of all, thank you very much to my teacher, Professor Liu Chenglin, and then ......"

Chen Xu wrote two words on the LCD panel of the podium.

The LCD panel is connected to the large screen behind him, and it is: recursive!

Chen Xu raised it and said, "What I want to talk about today is the role of matter recursion in semantic analysis!"

But there is a difference between the recursion of matter that I am talking about and the recursion of matter as you understand it.

As you know, in the grammar of the language we see recursion, we see recursive geometric trees that grow upwards forever, and we also see a way to introduce recursion into the theory of solid state physics.

Now, let's think differently, in which the whole world is built on recursion. ”

Speaking of this, Chen Xu paused for a moment, and then said: "I once considered a question, that is, can I design a programming language that allows some kind of inaccuracy?

It has to guess the program's intentions.

To understand what is done outside the rules of language......"

A foreigner in the audience raised his hand to ask a question.

Chen Xu smiled: "Please speak." ”

Foreigner: "I know you're referring to that kind of flexible language, but since you're all wrong, what's the point of such a program?"

Chen Xu: "Of course it makes sense. I've been asked this question, and I'm repeating it now, it's a mistake within the rules, so it's no longer a real foul, because it's already within the rules.

In fact, I've written one of these elastic languages, and based on this language, I've developed a protective wall, it's called Sword and Shield!"

Both Chinese and foreign professors in the audience were shocked when they heard this.

"What? It's already in practice? How is that possible?"

"It's nonsense! The concept of elastic language has been proposed for decades, and there has been no substantial development until now, and he dares to say that he has developed an elastic language with a yellow mouth?"

"Yes~ I think he's just a ......"

For a while, there was a lot of discussion in the large conference room.

In the penultimate row, Jiang Qisen, who was sitting with Zhang Yao, said with a smile: "What's the matter, I'll just say that his level is limited."

He doesn't look at what kind of place it is?

Most of our domestic professors are not very good, and they were fooled by two concepts by him.

There are many authoritative professors from top foreign schools at the scene, and he is talking nonsense here, that is, looking for a slap in the face. ”

Zhang Yao hesitated for a moment and said, "You...... Go and see, Sword and Shield is a very powerful company. ”

"Sword and shield? hehe, I haven't heard of it. Jiang Qisen smiled, took out his hand to open the search engine, typed in "sword and shield", and then smacked, the page was densely packed with news......

Chen Xu patted the microphone, waited for the scene to be quiet, and said: "Everyone, don't be impatient, and then I will explain to you the design principle of flexible language."

I just talked about matter recursion, which involves the structure of elementary particles, such as electrons, protons, neutrons, and photons of tiny electromagnetic radiation quanta......

It's a Feynman pattern......"

Chen Xu spoke very slowly, and with pictures and texts, so that everyone on the scene could understand what he was talking about and what he was trying to say.

As the explanation deepened, a solemn look gradually appeared on the faces of the audience.

From the strength of Chen Xu's speech, they felt that what he said was probably true.

Chen Xu put a very complex pattern on the big screen, and then said: "This is the design idea diagram of the whole elastic language. At the same time, it is also named CX language by me. ”

And "CX" is the pinyin abbreviation of Chen Xu's name.
